    Publication . Castro, Manuel; Díaz-Orueta, Gabriel; Alves, Gustavo R.; Fidalgo, André Vaz; García-Zubía, Javier; Hernández-Jayo, Unai; Pester, Andreas; Zutin, Danilo; Kulesza, Wlodek; Gustavsson, Ingvar; Pozzo, María I.; Dobboletta, Elsa
    In 2015, Electrical and Computer Engineering Department (DIEEC) of the Spanish University for Distance Education (UNED) in Spain started to- gether with the Santiago del Rosario National University (UNSE, Argentina) and with the support of the Research Institute of Education Sciences of Ro- sario (IRICE-CONICET, Argentina) under the Coordination of the Polytechnic Institute of Porto (IPP, Portugal) the new development and deployment of the VISIR system inside the UNSE University as part of the VISIR+ Project. The main objective of the VISIR+ Project is to extend the current VISIR net- work in South America, mainly in Argentina and Brazil, with the support and patronage of the European Union Erasmus Plus program inside the Capacity Building program and as part of an excellence network future development in- tegration framework. This extension of VISIR nodes reconfigure in 2016 a new project, PILAR, that as part of the Erasmus Plus projects will allow the Strategic Partnership to develop a new federation umbrella over the existing nodes and network.

  • Electronics remote lab integration into a MOOC – Achieving practical competences into MOOCs
    Publication . Loro, Felix Garcia; Sancristobal, Elio; Gil, Rosario; Diaz, Gabriel; Castro, Manuel; Albert-Gómez, Maria José; Alves, Gustavo R.
    Massive Open Online Courses (MOOCs) phenomenon introduces a new philosophy in educational models. Regardless of users’/students’ motivation when enrolling (lifelong learning, educational support, interest in new educational areas, etc.), MOOCs expand the ways of reaching knowledge. Flexibility is one of the key aspects of this new educational methodology. This flexibility has to be expanded/translated to all the aspects/features of the course. For educational institutions, traditional approaches must be left behind when designing courses and must provide a new approach to educational process. MOOCs fit very well to several areas of knowledge. However, they involve significant challenges for science MOOCs to be really effective, especially in developing courses. These educational challenges are highlighted in courses which need to offer practice-oriented learning in order to build successful crosscurricular capabilities and abilities. Nowadays, educational institutions trust in experimentation as one of the pillars in which learning is based. In fact, theoretical models used in books and in traditional classrooms just try to bring closer to students the actual behavior of real systems. Unfortunately, it is not possible to provide students with a laboratory in a totally/one hundred percent remote learning environment. This paper deals with the results of the integration of a remote laboratory in a MOOC; how it has been taken advantage of VISIR pros and how its cons have been solved, as well as the evolution of the global system (LMS+VISIR) in continuous improvement.

    The PILAR (Platform Integration of Laboratories based on the Architecture of visiR) Erasmus Plus project started in September 2016 and will last three years. The core of the PILAR project is the VISIR remote laboratory —Virtual Instruments System In Reality—. The project aims for a federation of five of the existing VISIR nodes, sharing experiments, capacity and resources among partners, and to provide access to VISIR remote lab, through PILAR consortium, to students from other educational institutions. PILAR will be the framework from which management tasks will be performed and laboratories/experiments will be shared. PILAR will also foster the Special Interest Group of VISIR under the Global Online Laboratory Consortium (GOLC) of the International Association of Online Engineering (IAOE).

    Experimenting is fundamental to the training process of all scientists and engineers. While experiments have been traditionally done inside laboratories, the emergence of Information and Communication Technologies added two alter-natives accessible anytime, anywhere. These two alternatives are known as virtual and remote labs, and are sometimes indistinguishably referred as online labs. Sim-ilarly to other instructional technologies, virtual and remote labs require some ef-fort from teachers in integrating them into curricula, taking into consideration sev-eral factors that affect their adoption (i.e. cost) and their educational effectiveness (i.e. benefit). This chapter analyses these two dimensions and sustains the case where only through international cooperation it is possible to serve the large num-ber of teachers and students involved in engineering education. It presents an ex-ample in the area of Electrical and Electronics Engineering, based on a remote lab named Virtual Instruments System in Reality, and it then describes how a number of European and Latin-American institutions have been cooperating under the scope of an Erasmus+ project2, for spreading its use in Brazil and Argentina.

    Experimental activities with real components are an essential part of all courses including or devoted to electrical and electronic circuits theory and practice. The knowledge triangle composed of hand-written exercises, simulations and traditional lab experiments has been enriched with the possibility for students to conduct real experiments over the Internet, using remote labs. This tutorial is devoted to one such remote lab named Virtual Instrument Systems in Reality (VISIR). The Global Online Laboratory Consortium (GOLC) elected VISIR as the best remote controlled laboratory in the world, at the first time this distinction was awarded. At the end of this tutorial, attendees are expected to know what is VISIR, what can (not) be done with it, who is currently using it, and how can one integrate it in a given course curriculum.

  • New Scenarios and Trends in Nontraditional Laboratories From 2000 to 2020
    Publication . Fernandez, Ricardo Martins; Garcia-Loro, Felix; López-Rey, Africa; Meier, Russ; Castro, Manuel; Alves, Gustavo
    For educational institutions in science, technology, engineering and mathematics (STEM) areas, the provision of practical learning scenarios is, traditionally, a major concern. In the 21st century, the explosion of information and communication technology (ICTs), as well as the universalization of low-cost hardware, has allowed the proliferation of technical solutions for any field, in the case of experimentation, encouraging the emergence and proliferation of nontraditional experimentation platforms. This movement has resulted in enriched practical environments, with wider adaptability for both students and teachers. In this article, the evolution of scholar production has been analyzed at the global level from 2000 to 2020. Current and emerging experimentation scenarios have been identified, specifying the scope and boundaries between them.

    Publication . Garcia-Loro, Felix; Cristobal, Elio San; Diaz, Gabriel; Macho, Alejandro; Baizan, Pablo; Blazquez, Manuel; Castro, Manuel; Plaza, Pedro; Orduna, Pablo; Auer, Michael; Kulesza, Wlodek; Gustavsson, Ingvar; Nilsson, Krostian; Fidalgo, André; Alves, Gustavo R.; Marques, Maria Arcelina; Hernandez-Jayo, Unai; Garcia-Zubia, Javier; Kreiter, Christian; Pester, Andreas; Garcia-Hernandez, Carla; Tavio, Ricardo; Valtonen, Kati; Lehtikangas, Elina
    Social demands have promoted an educational approach based on an “anywhere and anytime” premise. Remote laboratories have emerged as the answer to the demands of technical educational areas for adapting themselves to this scenario. The result has not only benefit distance learning students but has provided new learning scenarios both for teachers and students as well as allowing a flexible approach to experimental topics. However, as any other solution for providing practical scenarios (hands-on labs, virtual labs or simulators), remote labs face several constraints inherited from the subsystems of its deployment  hardware (real instruments, equipment and scenario) and software (analog/digital conversions, communications, workbenches, etc.). This paper describes the Erasmus+ project Platform Integration of Laboratories based on the Architecture of visiR (PILAR) which deals with several units of the federation installed in different educational institutions and devoted to analog electronics and electrical circuits. Based on the limitations of remote labs, the need for the federation will be justified and its benefits will be described by taking advantage of its strengths. The challenges that have come up during the different stages and the different approaches to design are also going to be described and analyzed
